Leviticus 8:30-32

³⁰And taking the ointment, and the blood that was upon the altar, he sprinkled Aaron, and his vestments, and his sons, and their vestments with it.

³¹And when he had sanctified them in their vestments, he commanded them, saying: Boil the flesh before the door of the tabernacle, and there eat it. Eat ye also the loaves of consecration, that are laid in the basket, as the Lord commanded me, saying: Aaron and his sons shall eat them:

³²And whatsoever shall be left of the flesh and the leaves, shall be consumed with fire.
